Albedo Characteristics of Degraded Grassland Ecosystem in the Source Region of Three Rivers in Qinghai-Tibetan Plateau
青藏高原三江源区退化草地生态系统的地表反照率特征

To examine the albedo characteristics of degraded grassland ecosystem in the source region of the three rivers in the Qinghai-Tibetan Plateau,the seasonal and diurnal variations of albedo and its affecting factors were studied using the data measured from December 2006 to November 2007. The annual average albedo of degraded grassland ecosystem was 0.25,with the average value of 0.18 in growing season (from May to September) and 0.25 in non-growing season. In the early of growth season,the albedo was dominat...
